G'day, and thianks lot alloy cleaning tips and for the reverse idea.
Although my Trike looks alike a three wheeled car it is in fact a motorcycle and is registed as one, which is a good thing because if it were a car the ADR's are much stiffer.
and bike engine means no emissions to worry about, it all may change in the future mind.
I'm sure many of you would have known or heard of Ron Hewitt, he was a great mate of mine and built our trikes around the same time, he finished before me, his reverse consisted of a ring gear
and starter motor mounted on the drive shaft just behind the engine, man that reverse kicked up a racket, it worked but I doubt it would go very far up an incline.
My reverse will have an Elite racing transmissions reversing G/Box inline with the drive shaft, see the pic of the box along with the hardie spicer slip yoke and other bits, Joe.
